## General troubleshooting

If you are having issues, be sure to try these general tips first:

### USB Control Center can't find a compatible Router

1. Is the router turned on? The AC adapter may be unplugged. Check that the Power LED is lit.
2. Make sure your computer’s wireless adapter and/or access point is configured properly and note the configuration settings, paying special attention to the wireless mode, SSID or network name, and security.
3. Make sure you have a good wireless signal from the Wireless Access Point or Router to your computer, and that it is away from metal objects and devices that generate radio interference (like Bluetooth devices, cordless phones, and microwave ovens).
4. Is the network cable connected properly? If you are on a wired network, the network (LAN) cable may be unplugged or have bad contacts. Verify the cable connections.
5. Is your computer on the network? Try to see if you can connect to other network computers or if you can browse the Internet. Verify that the network is working properly.

### Disks not appearing in Windows Explorer or OS X Finder, or other devices not appearing in the USB Control Center

1. Is the USB cable connected properly? The USB cable may be unplugged or have bad contacts. Verify the cable connections.
2. Is the USB disk drive format supported? Routers support FAT16, FAT32 and NTFS formatted disk drives only. If you have a disk you want to connect which has a different file format, you can still connect to it in Network USB mode or you can reformat the disk to FAT32 or NTFS and use it in Network Storage Mode.
3. Does the device work correctly when directly connected via the USB connection to your computer?
4. Ensure direct USB connection work properly before using SX Virtual Link. If you are having any difficulties, please make sure your USB device works when connected directly with a USB cable to your computer before trying to use the Control Center. If the device doesn't work directly over USB to your computer, it won't work when connected with this feature.

### Unreliable operation

1. Did you install any software just before your trouble occurred? The new software may be causing a problem. Remove the software you installed and re-install it.
2. Does the same problem occur after rebooting your PC? Rebooting the PC may solve the problem.

## Device troubleshooting

If a device is visible in the USB Control Center, but you cannot connect to it, your firewall may be blocking the connection. During installation, the software configures the Windows firewall to enable your Router to operate properly, but if you are running a third-party firewall, you may need to specify settings to open a port and enable operation of the Router with the software. For information on how to do this with several types of popular firewalls, see firewall settings.

## Printer troubleshooting

When sharing a printer, the correct driver must be selected in the device properties Connections tab. For more information, see printer connections.

## VPN troubleshooting

The USB Control Center may not work with VPN (Virtual Private Network) as VPN filters the connection between the computer and other network devices. If you have VPN enabled and the software does not work, please turn off the VPN connection.
